I'd never heard of Verastarr or their cables until a month ago, when my brother in-law sent me a pair of the grand illusions for Christmas. I swapped them out my old audioquest type 4 cables. The difference in sound for me was pretty dramatic. I love them. I have Magnepan MMG type speakers with a couple of custom mods and they sound amazing. I have not switched cables back and forth, so that's about all I can say, but I really like them.
